Abstract: ABSTRACT OF THE DISCLOSURE             A latent image of an object which appears to be invisible to the  unaided eye is formed on a substrate by photographing the object through a half tone screen to produce at least one halftone image of the object, thereafter placing the halftone image in reg-istry with a strip of light sensitive film and a dark screen having therein a plurality of extremely small apertures arranged in parallel rows oriented in predetermined angular offset relation, for instance 30° to the rows of halftone dots forming the halftone image, exposing the strip of film to the halftone image through the small openings in the screen, developing the exposed film to produce thereon the latent image of the object, and then imprinting the latent image on said substrate.  The printed image can be viewed through another dark screen having apertures smaller than those in the first-named screen, and will appear automatically on the face of any print made of the substrate by means of a xerographic process or the like.

Abstract: GRAVEL SPREADER               ABSTRACT OF THE DISCLOSURE An Apparatus for spreading loose material, such as gravel, on a surface.  The apparatus comprises an elongate material spreader for positioning generally parallel to the surface a distance above the surface.  A frame extends forwardly and above the spreader to a pivotal connector for connecting the apparatus to a hopper trailer between the trailer and the surface.  A first material retainer extends forwardly from the front of the spreader near one end of the spreader.  A second material retainer extends forwardly from, the front of the spreader.  The first retainer is posi-tionable a distance from the second retainer so that, when the material is distributed from the trailer a distance from the front of the spreader in a forward direction, the material is spread between the first and second retainers and between the bottom edge of the spreader and the surface, as the trailer moves in the forward direction along the surface.

Abstract: ABSTRACT     An implement hitch assembly pivotally attached to the rear of a self-propelled pulling vehicle. The hitch assembly tows a front agri-cultural implement and a rear agricultural implement in a tandem position when traveling on a roadway. By releasing a front latch and at the same time releasing a cable that holds a rear wheel, the forward movement of the implements towed behind the pulling vehicle allows the rear wheel to fall back and moves the rear implement in a side-by-side position with the front implement when the implements are to be used in the field.          When the implements are in a side-by-side position, the rear implement may be moved back to a tandem position with the front implement by re-leasing a rear latch.

Title: Process for preparing polyethylene terephthalate  useful for beverage containers
Inventor: HALEK GEORGE W
IPC: B65D1/00
Filed: 1979-05-16
Granted: 1982-07-27
Abstract: ABSTRACT OF THE DISCLOSURE         There is disclosed a process for reducing the acetal-dehyde content and the generation rate of acetaldehyde of poly-ethylene terephthalate chip which has a crystallinity of at least about 30% in order to render the polyethylene terephthalate suitable for making containers which are useful in the carbonated beverage industry.  This process comprises stabilizing the poly-ethylene terephthalate by heating it at an elevated temperature in air and maintaining an air to chip ratio at a predetermined value of at least about 0.8 standard cubic foot of air per minute/pound of resin per hour and at a vapor velocity of at least about 0.5 foot per second.  The air used in the stabiliza-tion process has a dew point of less than about -30 C.  The stabilized polyethylene terephthalate produced by this process has an acetaldehyde level of less than about 2.5 parts per mil-lion, a generation rate of acetaldehyde of less than about 3.0 parts per mullion per minute and an intrinsic viscosity of from about 0.60 to about 0.95 deciliters per gram.  There is also disclosed a process for molding a polyethylene terephthalate preform comprising melting the above described polymer, forming it into the desired preform shape, and cooling the molten poly-mer.  This preform may then be reheated above its glass transition temperature and molded into the desired container shape.

Abstract: PRE-INSERTION RESISTOR MECHANISM FOR A CIRCUIT INTERRUPTING DEVICE           ABSTRACT: A pre-insertion resistor mechanism for a circuit interrupting device of the type which has a pair of normally-engaged contacts.  One of the contacts is movable relative to the other contact in an arc-extinguishing environ-ment to selectively separate the contacts to open a gap there-between to effect circuit interruption.  The contacts are continuously, electrically connected to respective, opposed circuit-connectable terminals on the device.  The pre-insertion resistor mechanism includes a pre-insertion resistor electrically connected at one end to one of the terminals.  The other end of the resistor carries a stationary electrode.  A movable electrode assembly which is electrically connected to the other terminal is mechanically coupled to the movable contact so that upon movement thereof to open the gap, the movable electrode simul-taneously separates from the stationary electrode.  After a predetermined amount of the movement of the electrode has taken place, a latch assembly uncouples the movable electrode assembly from the movable contact permitting the movable electrode assembly to move back toward the stationary electrode.  In this way, when the contacts are subsequently re-engaged, the movable electrode assembly leads the main movable contact so that the movable electrode assembly re-engages the stationary electrode prior to the engagement of the contacts.  Thus, the circuit is first made between the electrodes, whereat some arcing occurs, with the resistor in parallel with the gap between the main electrodes.  When the contacts re-engage, they again carry most of the current through the interrupting device.
